Worse design

Know nothing about is ok! And common too.

knowing what Paul B or lovesofa know is the challenge!

 

I modified the keel of an inflatable a few years back. Not sure of the term... I would call it bow tripping. In calm waters (only) and two people it would lunge and bow down enough that if the passenger was not aware he was easily thrown. Of course no where near submarining though.

 

One must get this very slowly, and whith every sense:

I modified the keel of an inflatable...............

Yes of course, one is not satisfied with the darn behaviour of a production boat, and what else can one do? One modifies the crap. Nothing as easy as that.

The rest of the post, I did not read.
Translate it to me if it´s worth, please my peers.


Sometimes I would like to kick their asses, sometimes, when it is in the more serious threads, I would like to beat their dumb moule.

And sometimes I am happy I can switch this off. And no Kistinies, Paul B´s , and lovesofa´s are part of my life. In a second!

What th

Zappi. can understand a modified hull being capable of doing that, but a production boat should not do this while while simply cruising down a river, or so i think:

Here is a pretty tough situation:

The OZ boat broke in half with John Bertrand at the helm in Dago ( in deep water)
Went down in about a minute.

I would agree the whole world of sailing knows about that i'm sure its on youtube

 

I am not impressed with the nature of the argument



any fool or even well seasoned mariner can submarine a over powered boat


also is important to follow basic safety procedures

 

Boston
good example ( in Oz) on the top and that happens a lot.
But it happens as the boat is 'on top if the water' and not 'in it' as slow production tubs are therefore you can find yourself going down hill.

Bottom possibly a good example of a stepped v bottom in a turn and hence their reputation.

 

might it be that there was to much weight put in the bow? did the driver back off the gas? with that much weight up front and a bluff bow acting as a break coming off a wave , would stop it quick . *** up nose down.

 

Here's a tough contender:http://www.riemurasia.net/jylppy/media.php?id=60946&c=11

Atleast when speaking about an abused design.

 

No, No, no. The top boat is nothing to do with too much power, Bos. It has stuffed because of too much weight in the stern. When it comes down, it trips and causes that. If there were more power and the throttleman was just coming back on, it might not have happened. I think new, computer controlled fuel will be seen as saving the work of a throttleman but a human can anticipate and (It's a guess) the delay with a system that judges how much fuel to inject by load will cause more of this, i.e., the throttle needs to be coming up right as that prop touches down. All IMO.
With the second boat the TV announcer suggested the need for safety belts. Dubious. I do know that to drive at speed requires more feel than a novice possesses. Things happen quick at seventy. The knuckleheads in the river sled threw it into reverse again - hardly a design flaw.

I've never seen that! Kids with too much time and money!

There's no doubt it was a bad design for the conditions it
actually experienced on that day.
And it was also a poor decision to design for conditions
that were less severe than they experienced.

But was it a good design for less severe conditions?

-where does the motor go? An outboard would ruin those elegant lines.

 

Thats like criticising a boat because you have to leave the cockpit to moor it. Any pilot who has flown a Spittie will tell you it was a delight in the air, where it counted. You only had to raise the u/c once per flight; the controls you actually needed were all to hand.
